Convective heat transfer

From Thermal-FluidsPedia

The second mode of heat transfer is convection, which occurs between a wall at one temperature and a moving fluid at another temperature. The mechanism of convection heat transfer is a combination of random molecular motion (conduction) and bulk motion (advection) of the fluid. Convective heat transfer depends on many factors including fluid properties, flow velocity, geometric configuration, and any fluid phase change that may occur as a result of heat transfer.
